data dependent logic swing internal bus architecture for ultralow power lsi s
IEEE Journal of Solid-state Circuits, 1995Co-Authors: Mitsuru Hiraki, Hirotsugu Kojima, H Misawa, T Akazawa, Yuji HatanoAbstract:A reduced-swing internal bus scheme is proposed for achieving ultralow-power LSI's. The proposed data-dependent logic swing bus (DDL bus) uses charge sharing between bus wires and an additional bus wire to reduce its voltage swing. With this technique, the power dissipation of the proposed bus is reduced to 1/16 that of a conventional bus when used for a 16-b-wide bus. In addition, a dual-reference sense-amplifying receiver (DRSA receiver) has been developed to convert a reduced-swing bus Signal to a CMOS-Level Signal without loss of noise margin or speed. Experimental circuits fabricated using 0.5-/spl mu/m CMOS process verify the low-power operation of the proposed bus at an operating frequency of 40 MHz with a supply voltage of 3.3 V. >

960 km ssmf transmission of 1057 gb s pdm 3 pam using directly modulated vcsels and coherent detection
Optics Express, 2013Co-Authors: Chongjin Xie, Po Dong, Peter J Winzer, C Greus, M Ortsiefer, Christian Neumeyr, Silvia Spiga, Michael Muller, M C AmannAbstract:We generate a 105.7-Gb/s Signal by directly modulating a 1.5-µm VCSEL with a 33.35-Gbaud 3-Level Signal and polarization multiplexing. By using digital coherent detection, we successfully transmit the 105.7-Gb/s line rate (88.10 Gb/s net bit rate) Signal over 960-km standard single-mode-fiber (SSMF) at a 20% hard-decision forward-error correction (FEC) threshold, which is at bit-error ratio (BER) of 1.5x10−2.

Origin of the two-dimensional electron gas at the CdO (100) surface
Physical Review B, 2019Co-Authors: Pip C. J. Clark, Andrew I. Williamson, Nathan Lewis, Ruben Ahumada-lazo, Mathieu G. Silly, James J. Mudd, Christopher Mcconville, Wendy R. FlavellAbstract:Synchrotron-radiation angle-resolved and core-Level photoemission spectroscopy are used together to investigate the origin of the two-dimensional (2D) electron gas on the surface of single-crystal CdO (100) films. A reduction in the two-dimensional electron density of the surface state is observed under the synchrotron beam during angle-resolved photoemission spectroscopy, which is shown to be accompanied by a concomitant reduction in the surface-adsorbed species (monitored through the O 1s core-Level Signal). This shows that surface adsorbates donate electrons into the surface accumulation layer. When the surface is cleaned, the surface conduction band state empties. A surface doped with atomic H is also studied. Here, interstitial H increases the two-dimensional electron density at the surface. This demonstrates that reversible donor doping is possible. The surface band-bending profiles, 2D electron densities, and effective masses are calculated from subband dispersion simulations.
